What Renewable Energy Wildlife Institute does
Mission
Through science and collaboration, accelerate responsible deployment of renewable energy to mitigate climate change and protect wildlife and ecosystems.
As stated on its FY2024 Form 990.
Programs
Research program management: rewi's research program is designed to answer key questions to inform policy with sound science and facilitate permitting processes as it relates to wildlife for utility-scale wind and solar energy infrastructure. The program is informed by key research priorities outlined in discussions with industry, state and federal agencies, and conservation/science organizations, and rewi's work is multiplied through collaborations with over 100 scientists around the world. Rewi's research hub serves as a central location for available information on renewable energy and wildlife including publications, websites, datasets, programs, and organizations. The hub improves accessibility of information and is instrumental in identifying at-risk species and informing research priorities. The hub also includes rewi's technology catalog, a library of existing and developing technologies with applications for monitoring and minimizing wildlife conflicts at renewable energy facilities.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2018 to 2019, from $3.0M to $5.1M (+71%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 13% · 2021 15% · 2022 20% · 2023 16% · 2024 7%. Grants only. Government contracts and fees sit inside program revenue.
83% of RENEWABLE ENERGY WILDLIFE INSTITUTE’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 4 funders, grant income rose $65k → $311k.
4 of 14 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 17% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of RENEWABLE ENERGY WILDLIFE INSTITUTE’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
RENEWABLE ENERGY WILDLIFE INSTITUTE has a broad base — no single funder exceeds 31% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
84% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund RENEWABLE ENERGY WILDLIFE INSTITUTE.
Largest funder’s share by year: 2017 77% · 2018 73% · 2019 100% · 2020 59% · 2021 49% · 2022 75% · 2023 97% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
30% of RENEWABLE ENERGY WILDLIFE INSTITUTE's funders are still giving 3 years after their first grant; 50% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
RENEWABLE ENERGY WILDLIFE INSTITUTE draws 79% of its grant income from funders outside Washington, D.C., across 4 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $163k arriving through sponsors registered in 4 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
RENEWABLE ENERGY WILDLIFE INSTITUTE holds deeper cash reserves than three-quarters of the 2,186 environment nonprofits its size.
